Objective To study the interaction between ?_1-antichymotrypsin (ACT) and amyloid peptide A?_~1-42 in vitro, and the effects of their complex on expression of transcription factors PPAR? and NF?B in human neuroblastoma (Kelly) cells. Methods A?_~1-42 and ACT were mixed at a 10∶1 molar ratio at room temperature, the complex formed in 2 hours and 24 hours were expressed as A?_~1-42 /ACT (2 hours), A?_~1-42 /ACT (24 hours), respectively. The complexes were studied by using agrose electrophoresis, and their effects on PPAR? and NF?B expressions were assessed by electrophoresis mobility shift assay (EMSA). Results At conditions used, ACT interacted with A?_~1-42 in vitro, the complexes formed and functioned differently according to their interaction period. Compared with unstimulated control cells, A?_~1-42 /ACT (2 hours) strongly increased PPAR? and NF?B expressions by Kelly cells by 158% (P

Objective:To observe therapeutic effect of aerobic exercise on blood pressure and vasoactive mediators in patients with isolated diastolic hypertension (IDH).Methods:A total of 93 recently diagnosed IDH patients were se- lected and randomly divided into exercise intervention group (n=47,received aerobic exercise,twice/d,50~80 min/time for six months)and control group (n=46,didn't receive aerobic exercise).Office blood pressure (OBP), ambulatory blood pressure monitoring (ABPM)and levels of vasoactive mediators were measured and compared be- tween two groups before and six months after intervention.Results:There were no significant difference in levels of OBP,ABPM indexes and related vasoactive mediators between two groups before intervention (P>0.05 all).Com- pared with before intervention,after six-month intervention,there were significant reductions in levels of office di-astolic blood pressure (ODBP),mean DBP (mDBP),daytime DBP (dDBP)and nighttime DBP (nDBP)in both groups (P<0.05 or <0.01);compared with control group,there were significant reductions in levels of ODBP [(89.23±14.70)mmHg vs.(79.26±13.18)mmHg],mDBP [(86.51±14.30)mmHg vs.(77.20±12.45)mm- Hg],dDBP [(87.93±12.16)mmHg vs.(78.02±11.27)mmHg]and nDBP [(83.18±12.57)mmHg vs.(74.22 ±11.36)mmHg]in exercise intervention group,P<0.05 all.Compared with control group,after six-month inter- vention,there were significant rise in levels of adrenomedulin (AM)[(36.75±5.13)ng/L vs.(47.59±6.82)ng/L]and prostaglandinI2 (PGI2)[(89.55±16.31)ng/L vs.(99.24±18.20)ng/L],and significant reductions in levels of angiotensin Ⅱ (AngⅡ)[(98.30± 15.65)ng/L vs.(91.28±17.40)ng/L]and thromboxane A2 (TXA2 )[(93.61±15.27)ng/L vs.(80.24±12.31)ng/L]in exercise intervention group,P<0.05 all.Conclusion:Aer- obic exercise can significantly lower blood pressure and correct vasoactive mediator level disorder in IDH patients.

Objective Analysis the clinical data of high-EuroSCORE 114 patients due to ronary surgery to elucidatethe surgical advantages between on-pump and off-pump CABG.Methods From September 2008 to March 2011,114 highEuroSCORE patients due to coronary surgery were randomly divided into off-pump group 48,and on-pump gronp 66 cases.Preoperative,intra-operative and peri-operative clinical data of all the patients were collected.All patients were followed up for 1 month postoperatively.Results The baseline of the two groups had no significant difference.Application of internal mammary artery,positive inotropic drugs and IABP assistance between the two groups were similar,P >0.05,Compared with the offpump group,patients in on-pump gnup had longer operation time,hut more graft counts and a higher rate of revascularization [ (3.71±0.55)gnifis vs.(2.82±0.39)grafts ],P < 0.05.There were no significant differences of peri-operative mortality and post-operative complications between the two groups,P >0.05.The patients in on-pump group had more post-operative chest drainage in the first 24 hours[ (875.0±134.2)ml vs.(589.4±102.5)ml] and blood transfusion[ (656.3±84.4)ml vs.(433.3±62.9) ml ] compared with the off-pump group,P < 0.05.The data of l-month follow up denonstrated that echocardiographic data,NYHA and symptoms of angina of the two groups had no significant difference,P > 0.05.Conclusion Compared with OPCAB,CCAB did not increase postoperative renal failure,neurological complications and lung injury in highrisk patients,but had more complete revascularization.The disadvantage of CCAB was postoperative bleeding,blood productsuse.

Objective To investigate the role of nuclear factor(erythroid?derived 2)?like 2(Nrf2)in load?driven bone metabolism in Nrf2 knock?out(KO)mice. Methods The hybridized mice in the same brood were selected through PCR detection and were divided into two groups,i.e.,the Nrf2 knockout(KO)group and the wild?type(WT)group. Ulna of mice was loaded with 4 000 peak microstrains at 2 Hz for 3 consecutive days (120 cycles/day)as scheduled,the relative mineralizing surface(rMS/BS)and the relative bone formation rate(rBFR/BS)of ulna were measured for the two groups. Results Load?induced bone formation was suppressed in KO mice. Compared to the WT control,the relative bone formation rate was roughly 84%lower in KO mice(P<0.01). Conclusion The loss?of?function mutation of Nrf2 in bone diminishes load?driven bone formation.

Purpose To explore the multislice spiral CT (MSCT) features of renal chromophobe carcinoma, and to improve the understanding and diagnosis of the disease. Materials and Methods MSCT features of 17 patients with renal chromophobe carcinoma confirmed by surgical pathology were retrospectively analyzed, plain MSCT and multi-phase dynamic contrast-enhanced scan were applied to these patients. Results Single substantive round or oval-shaped soft tissue mass was demonstrated in 17 cases. The lesions were all uniform density on plain MSCT, and mild to moderate homogeneous enhancement in 11 cases on enhanced MSCT, including 9 cases with significant enhancement above the renal medulla and below the renal cortex, and 2 cases with similar enhancement to renal medulla in corticomedullary phase. On nephrographic phase the lesion showed significant lower density than renal medulla. Heterogeneous enhancement presented in 6 cased, including 1 case with small necrosis and 1 case with stellate scar lesion in low-density. Conclusion Renal chromophobe carcinoma demonstrates a round solid mass of uniform density on plain MSCT, and mild to moderate homogeneous and heterogeneous, which can provide the reference value for preoperative diagnosis.

Objective To observe the efficacy of using a semiconductor laser combined with short-wave ultraviolet rays(UV)to treat patients with herpes zoster. Methods Forty-two patients with herpes zoster in the Department of Dermatology of our hospital were randomly divided into two groups,with 21 patients per group. Patients in the control group were treated with conventional dermatology drugs and short-wave UV,whereas patients in the observation group were treated with conventional dermatology drugs and a semiconductor laser combined with short-wave UV. Re-sults After treatment for 7 days,the efficacy rate in the control group was 80.95%,whereas that in the observation group was 95.24%. The analge-sia time,scab time,and scab removal time were significantly shorter in the observation group than in the control group(P<0.05). The results of the pain assessment(visual analog scale )showed that the score of the observation group after treatment was significantly lower than that of the con-trol group(P<0.05). Conclusion Therapy involving a semiconductor laser combined with short-wave UV for patients with herpes zoster can be more effective than therapy with only a short-wave UV laser in promoting herpes healing,relieving neuralgia,and improving quality of life.

Objective To evaluate cardiac function after transplanting autologus monouclear bone marrow cells(MBMCs) in patients with myocardial infarction by echocardiography and Doppler tissue imaging. Methods Six male patients with myocardial infarction who need coronary artery bypass procedure were prospectively studied. Before cell transplantation and in the follow-up, echocardiography and Doppler tissue imaging was performed to observe the regional and global cardiac function of the patients, including infarction wall thickness(IWT), infarction wall movement velocity(IWMV),left ventricular end-diastolic diameter(LVDd), left ventricular end-systolic diameter(LVDs),left ventricular ejection fraction(LVEF), left ventricular shorting fraction(LVFS), ischemic mitral regurgitation. ~ 99m Tc-MIBI SPECT examination included immediate and prolonged image scors. Results After transplanting autologus MBMCs,IWT was increased compared with that before cell transplantation(P
